    • 單氣泡聲致發光是一種當氣泡被侷限於壓力場時,因強烈周期性震盪引致內部氣體溫度升高而發光的一種現象. 此一現象對甚多參數都非常敏感. 在本篇論文中,我門試著討論亮度,液體溫度,施加壓力,溶解氣體和它的亮度變化與時間的關係.
    我們是台灣第一個有系統研究此一現象的團隊,並試著建立一套足以重複他人已做過的實驗的系統以為將來高等量測的基礎.

    Single Bubble Sonoluminescence (SBSL) is a phenomenon occurs when a bubble trapped in a applied acoustic field, oscillates periodically in liquid and collapses so forceful that energy focus inside the bubble leads light emission. SBSL is very sensitive to many parameters. In this paper, we try to clarify the relation between brightness and temperature, driving force, dissolve gas and time evolution.
    We are the first team in Taiwan to research this program systematically, and try to build a system to repeat other’s doing for future deeply research.
